1. A schematic diagram of the sacral nerve stimulator has been added to the standard pelvic model.The implantation of a sacral nerve stimulator is a minimally invasive surgical procedure used to treat lower urinary tract and pelvic floor dysfunction diseases.

2. The pelvic model comes from the Z-Anatomy project, an open-source project that makes it easy to view the human anatomical structure.

3. The electrodes of the sacral nerve stimulator are placed in the third sacral foramen, in the form of a small ball, which is convenient for printing and observation.

4. Due to the placement reason, the directional model of the sacral nerve stimulator appears rough. You can try adjusting the placement in the opposite direction.

5. This is solely for popular science about the principle and anatomical location, and is not intended for any other purpose.
